The life of a hi-mileage K12GT

Ive been on this forum for many years but rarely post, frankly because I was too lazy to add my input. I feel I owe this form some payback so I am doing an experiment. ....

I just bought an 07 K12GT with 86,xxx miles on it in central Texas, I am the third (or fourth) owner, bike has never been in an accident, needs a clutch, and I know most of the history.

What Im trying to do is give an un-biased description of the service needed and reliability expected when the 2nd-Gen K bikes reach past 100k miles. Hopefully it may help current hi-mileage users and prospective buyers fear or eliminate fear of buying a high-mileage K-bike.

A quick search on ebay reveals that many of these bikes have been blown by the cam chain issue, and thus parts are relatively cheap....

A little backround about me, early 50's riding since 12- have had between 150-175 bikes in my lifetime, all brands (not many british) and truly like motorcycles in general, regardless of brand or type. I have also wrenched on all of my bikes since childhood and have had a bike repair shop for about 7 years in my 20s until I needed to grow up and get a real job. That being said, if you don't wrench on your own bike, don't buy an 2nd Gen K bike, it wont be cost effective for you. Otherwise if you dont mind doing your own work I feel this may be the best value ever in the sport touring segment.

I bought my 07 K12gt almost exactly 1 year ago with 41,000 miles. I now have a little over 63,000 miles on the bike. I have ridden this bike HARD and continue to do so almost daily. The bike has been my daily Houston commuter, long distance tourer and everything in between. I am the third owner of the bike and the previous owners both kept extremely good service records on my machine. The bike was always serviced at 2 local dealerships and all recalls were addressed. Since I've had the bike, it has never seen a dealership/shop. I do all of my wrenching and maintenance myself. I bought the bike knowing it needed a clutch. I replaced it myself at 45,000 miles and the bike has been bulletproof reliable ever since. The only things I've done to the bike have been oil changes, FD oil changes, brake services, bulbs and tires. I think the only other things I'm going to do are a manual chain tenisoner swap and spark plugs sometime within the next 10,000 miles. The bike is well on track to being a 100k+ mile-eater and I'd love to own it for as long as I can. I came from 3 BMW oilheads with a combined mileage of over 100,000 miles and so far, my gen 2 K-bike has been just as good to me as any of my boxers. I strongly believe that the key to the longevity/reliability of these bikes is to ride them as often as you can. Don't let the chain tensioner/seals run dry and make sure the jump guard had been installed. Wrenching on these machines isn't all that difficult or expensive either!

So here is the major service history of the bike:

In service date: 6/07 from Santa Fe BMW

New rear drive @ 10k miles on 4/09
Cam chain jumped tooth chain guard installed @32,100 miles on 1/13
Adjust valves/TB sync @46,500 miles on 3/14
Fuel pump ass'y replace under warranty @ 49,900 miles on 5/14
Wheel flange replace under warranty @ 51,400 miles on 8/15
ABS module goes out @ 51,400 miles- did not fix
Replace throttle cables @ 70k miles on 4/18
Adjust valves/spark plugs @ 70k miles on 4/18

We had a mini cold front blow thru Austin this past week (only mid 90s now) so I spent Saturday in the garage installing:

-New Barnet Clutch
-APE manual cam chain tensioner
-fixed broken latches on both saddlebags (biggest PIA job ever)

Rides and shifts a million times better now. Also noticed Ive got about .030" movement at 12 and 6 o"clock on rear drive. I guess with 76,500 miles on this drive I cant complain, so a new bearing is on order.

Next projects:

Install Ohlins front and rear picked up from ebay
Metal fuel line disconnect
Abs unit send to Module Master

Love my K1200RS’s currently 2, picking up a 3rd on Saturday.
Bertha I, 1998 Taxi with 57k miles, 54k mine came to me 11 years ago.
Lots of under 35k mile K1200RS/GTs for $3,500 or less.
An under valued bike for sure. At the same time my service log is in similar magnitude.
Enjoy updating your well loved K!
